Inspections And Maintenance - Bergey 24 VDC B Owner's Manual

Step 2:
Connect Dump Load leads. This is an optional
resistance-heating load that will operate when the
batteries are full. Polarity is not important in mak-
ing this connection.
The specification for the dump is 1 Ohm or higher,
with at least a 1,000 Watt capacity.
Step 3:
Connect Wind Turbine leads. The 60A circuit
breaker on the side of the circuit board should be
switched to "Off". Please ensure that the wind
turbine wires are connected with the proper polar-
ity. The system will not operate correctly and
could be damaged if the polarity is reversed. The
polarity can be checked with a Volt-Ohm-Meter,
but it does require that the XL.1 alternator be ro-
tated.
Step 4:
Connect Battery leads. Please ensure that the
battery leads are connected with the proper polar-
ity. The system will not operate correctly and
could be damaged if the polarity is reversed. Al-
ways check the polarity with a Volt-Ohm-Meter
before making connections.
The maximum current to the batteries will be ~ 60
amps with no PV and up to ~ 90 amps with the
maximum allowed PV array size. Wiring to the
batteries must be sized accordingly.
Step 5:
Connect PV leads. Please ensure that the PV
leads are connected with the proper polarity. The
system will not operate correctly and could be
damaged if the polarity is reversed. Always check
the polarity with a Volt-Ohm-Meter before making
connections.
The maximum current capacity of the PV regulator
circuit on the PowerCenter is 30 amps, or ap-
proximately 900 Watts.
Step 6:
Connect Inverter. If the system includes a DC to
AC inverter, connect the inverter input leads to the
battery terminals or DC source center, not to the
PowerCenter. The PowerCenter circuit board is
not designed to handle the high currents that are
possible with inverters.
Step 7:
Connect Loads. If the system includes 24 VDC
loads connect them to the battery terminals or DC
source center.
Step 8:
Reinstall the cover. Switch the 60A circuit breaker
to "On".
The XL.1 wind turbine system is now ready to op-
erate.

8. Inspections and Maintenance

The BWC XL.1 installation should be inspected
after 30 days and then again 180 days after instal-
lation. Following these two inspections the instal-
lation should be inspected every two years and
after any particularly severe weather. In corrosive
marine environments more frequent inspections
are recommended. Inspections should be done
on days when the wind is below 7 m/s (16 mph).
Check List for Inspections
1. Inspect each of the anchor points. Ensure
that all hardware is secure and the guy wires
are properly tensioned. Check to ensure that
no strands are broken.
2. Short the alternator using the procedure given
in the next subsection. Climb or lower the
tower. Always use proper safety belts and
lanyards when climbing.
3. Inspect the blades for:
A. Condition of the leading edge, particu-
larly out near the tip.
B. Tip damage.
4. Remove the spinner. Check the torque on the
blade nuts; the recommended value is 47 N.m
(35 ft-lbs). Check the front bearing cover for
seal integrity and grease loss. Reattach the
spinner and check that it is secure.
5. Check the screws holding the nacelle rubber
bumpers and tail fin in place.
6. Check the cotter pins and washers on the tail
pivot pin.
